The dictionary defines “post-truth” as “relating to or denoting circumstances in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief.”

In this case, the “post-” prefix doesn't mean “after” so much as it implies an atmosphere in which a notion is irrelevant — but then again, who says you have to take our word for it anymore?

Throughout a grueling presidential campaign in which accusations of lies and alternate realities flowed freely, in every direction, hundreds of fact checks were published about statements from both Donald Trump and Hillary Clinton.

Dozens of media outlets found that Trump's relationship with the truth was, well, complicated.

“Post-truth” was selected after Oxford's dictionary editors noted a roughly 2,000 percent increase in its usage over 2015 — it was appearing with far more frequency in news articles and on social media in both the United Kingdom and the United States.

“Post-truth” usage spiked again in July after Trump secured the Republican presidential nomination.

“It’s not surprising that our choice reflects a year dominated by highly-charged political and social discourse,” Grathwohl said. “Fueled by the rise of social media as a news source and a growing distrust of facts offered up by the establishment, post-truth as a concept has been finding its linguistic footing for some time.”

“Post-truth” was selected as the 2016 word of the year even before results of the election were known, said Katherine Martin, the head of U.S. dictionaries for Oxford University Press.

“We choose words that are going to highlight the interplay between our words and our culture,” Martin said. The final word of the year is meant to be one that captures the “ethos, mood or preoccupations of that particular year and to have lasting potential as a word of cultural significance.”

The Washington Post's own Fact Checker blog, which published 314 fact checks of the candidates who ran for president during the 2016 election cycle, has noted that “in many ways, it was an unbalanced race” — but didn't go so far as to endorse the term “post-truth.”

“I have never been a fan of the word 'post-truth,' since it’s a facile way to describe basic human behavior since the first words were spoken,” The Fact Checker's Glenn Kessler said in an email. “People have always been swayed by emotions and personal beliefs. As fact checkers, we give people the factual information and context for statements made by politicians. What people do with those facts is up to them.”

“Now I'm sure some of the word police, the 'wordinistas' over at Webster's, are gonna to say, hey, that's not a word,” said Colbert in the 2005 segment that introduced the word. “Well, anybody who knows me know that I'm no fan of dictionaries or reference books. They're elitist! Constantly telling us what is or isn't true. or what did or didn't happen.”

At the time, Colbert was still playing an exaggerated caricature of a conservative political-show host.

“Who's Britannica to tell me the Panama Canal was finished in 1914?!" he continued in the segment. “If I want to say it happened in 1941, that's my right. I don't trust books. They're all fact, no heart.”

Merriam-Webster made “truthiness” its 2006 word of the year.

And if anything, the rise of truthiness cleared the path for “post-truth,” as in: “In a post-truth world, truthiness is all that matters.”

“Given that usage of the term hasn’t shown any signs of slowing down, I wouldn’t be surprised if post-truth becomes one of the defining words of our time,” said Grathwohl, the Oxford Dictionaries president.

Each year, the Oxford staff selects hundreds of words, then narrows that list down through discussions about “what words are going to best highlight the ways in which the English lexicon is changing in response to current events,” said Martin, Oxford's head of U.S. dictionaries.

This year, the shortlist included “adulting” (often packaged into the phrase “adulting so hard,” as in, “I'm adulting so hard that I bought a leaf blower and increased my contribution to my 401(k) retirement savings plan”) and hygge, which refers to a “comfortable conviviality and feeling of contentment” central to Danish culture.

“Post-truth” also beat out finalist “alt-right,” a shortening of “alternative right” defined by Oxford as “an ideological grouping associated with extreme conservative or reactionary viewpoints, characterized by a rejection of mainstream politics and by the use of online media to disseminate deliberately controversial content.”
